Re: what is firefox nightly ? what is the difference between it and firefox browser ?

A brief description of each (in reverse order of development from Release to Nightly) - https://www.mozilla.org/en-US/styleguide/identity/firefox/channels/

You asked your question using the current Nightly version 26.0a1.

In order of development - some new features may come and go from channel to channel.

  • Nightly - Under heavy development. Least stable/secure. First tests of new changes/features; some changes/features introduced in Nightly may be removed before Release and other versions. Only for testing. Should only be used by very experienced users/testers.
  • Aurora - Still under development. More stable/secure than Nightly. Some bugs may still be present that need resolution. Should be used by experienced users only who can post/report reproducible problems and work around issues.
  • Beta - Final development stage before Release. Usually good stability/security. Major bugs resolved. Working out final bugs. Preview of what Release version will most likely contain in the way of changes/features, though some changes/features can still disappear before Release.
  • Release - Final channel released to public for everyday use.

Firefox. It is the release version.

For the average user for daily use, Firefox (Release) version is recommended. Current Firefox Release version is 23.0.1.

First, some advice.

To change channels, you must download and save the current version, close the browser, run the installer, accepting the defaults.

You may need to reinstall/transfer your extensions and transfer other important data (bookmarks, passwords, etc) IF a new Profile is created, or you can transfer them to your new Profile per the article below.
